I reserve the right, however, to employ the `mechanismherein described on'other types of scales.

In assembling the parts of a scale of this 'type it has been found to beextremely difficult to counterbalance the weight of the hand and tocounterbalance the weight ofthe link, because the adjustment of thecou'nterbalance of one of these parte: destroys the accu'- racy of thecounterbalance" of the other. e Hence experience has proved itadvisabley to adjust these counterbalances separately, as describedbelow. Furthermore, 'after' the scale is set up ready for'use and withthe.

hand standing accurately on the zero-line when the pendulum isperpendicular ity is often found on testing the scale that the hand doesnot accuratelyl register with all the inedge ofthemain pivot 7.

Vention consists in details of construction' dicating-lines onth'etable. Thisis due to the fact that the extremes ofv movement of thelink-pivot arejnot-in` proper relation tor a horizontal linedrawnthrough the active The' present indescribed Abelow in connectionwith a scale of the type illustrated herein 'and set "forth, 4vabove,rwherebythe difficulties just menl tioned can be 'overcome quickly,easily, ac` ourately, and permanently at the time 'fthe parts areassembled.v

The parts are then removed from the casing,.the-disk 960disconnected from the disk 96, the link-carrier inserted, the disk 960reattached, and the parts again'insertedin the casing. The link 11 isthen lmade vto connect the link-pivot 10*v with the scale-beamA 1, afterwhich the nut'18 is' adjusted on the screw'l7 to counterbalancethe'klink-pivot and link,and this adjustment is continued. untilfthehand againy stands Vac.

to ascertain if the active edge of the. hand f:

properlyregistersjwith'all lines on the table, Y'

tion to which the hand moves. If the-move` vand such test isveffected byplacing a known*v i Yweight on the platform and'noting thepovsiment isexcessive, it indicates that` the path of the link-pivot is too highrelative tothe main pivot, and if themovement of the'hand is notsufficient it indicates that the pathV of the link-pivot" is too low. Tocorrect either ofv these inaccuracies, oneof the screws'970 and 971 isloosened, while the other is tightened, which operation obviously rocksthe link-carrier slightly over the hub, andhence changes the relativeposition of the active edges of' the link-pivot and the main pivot,.

It is obvious that considerable change in and this can readily be donewithout'destro'ying vthe counterbalance of the handA or the I Y thedetails of construction may be made with-v out departing from theessential principle of my invention. The presentspecic'ation anddrawings describe and illustrate' only the manner I prefer atl-.thistime for carrying outv the Ageneral idea. It is clear that thevarious I'weights could be applied to and adjustablyy rigid and the adjustabilitylof `the other would probably sullce,4 'the link-carrier could befrockedioradju'stedaround the hub by other mechanism, one ofthe disksmight rpossibly 'held' on their'` supports in many 'different. Ways,either theweight 12 or. 120v mightv be' "ige 1 be entirely omitted andall the other parts carried by the remaining disk-the hand is as shownin dotted lines in Fig. 2-and many other changes in the construction ofparts and additions to the entire machine could be adopted withoutdetriment to the whole.
